BEARINGS: ENDURO angular contact cartridges with 440C stainless steel races and Grade 5 ball bearings.

The TorqTite bottom bracket line is Enduro's answer to problems with press fit designs. Forget glues/fixatives, paste, or tape to try and keep things quiet. This unique system uses a double-threaded internal sleeve to tighten the right and left cups using two spanner wrenches to torque the bottom bracket securely on installation. No more movement or internal fretting of your bottom bracket against your carbon fiber or aluminum frame--just a tightened mechanical system eliminating annoying and unwanted noises and internal friction that can also sap energy and wattage output. TorqTite guarantees perfect parallel alignment between the bearings even if the frame is not perfectly straight, eliminating lost energy.

Because of its unique thread-together design, this one bottom bracket works for both road ("BB86") and mountain (BB92) applications.

Two TorqTite wrenches are recommended for installation. For this particular bottom bracket (BB86/BB92), the RWC Outboard BB Cup Tool is also a very good fit. However, by purchasing two of the Torqtite wrenches, the ability to install and remove the PF30 version of this bottom bracket will also be acquired.
